Application filed April 18, 1904. Serial No. 203,798.

To all whom it may concern:-

Be it known that I, JOHN E. PAoKARD, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Delivery Mechanism for Vending Maclnnes, of which the following is a specification.

The invention relates to the support carrying the roller for discharging the vendable article and for centering the revoluble receptaclecarrying the vend able articles and to the means for givingthe roller the requisite yield and return to perform its ofiice.

The objects of the invention are to furnish a swinging and yield-able support for the dis charging and: centering-roller, by which the rollerwilt be positively moved toact as a dischargerand will be maintained in an elevated position to act as'a stop and centering devicewithout creating an undue amount of friction in its use; to: cause the roller to be returned under conditions that will not create any jar or recoil; to furnish a support for the roller formed in two sections, one section mounted on a rock-shaft and the other section mounted ona rock-shaft or rod carried by the first section and free to vibrate with the rockshaft or rod, and to improve generally the construction and operation of the several devices employed the making of the appara tus asa whole.

' The-invention consists in the featuresof construction and combinations of parts hereinafter described and claimed.

In the drawings only the operative mechanism relating to the control and positioning of the revollrble carrier or receptacle for the articles are shown, as. the invention relates particularly to this mechanism.

Figure l is a side elevation of the mechanism of the invention mounted on a plate for attachment within the case of thevendi-ngmachine; Fig. 2, a top or plan view of the mechanism shown in Fig- 1 with a coin receiver or cradle added; Fig. 3,a rear elevation; Fig. 4, a side elevation. showing only the support or cradle for the roller and the parts directly cooperating therewith; and Fig. 5, a

side elevation of the discharging mechanism whole in the arrangement shown is mounted on a base-plate A, which can be attached to the bottom of the casing of the machine by screws passing through holes a in the baseplate or in any other suitable manner. The plate A has mounted thereon a rock-shaft B, which shaft is supported in bearings 6, projecting upwardly from a plate 6, riveted or otherwise secured to the base-plate, so that the rock-shaft has a firm bearing and is free to be rocked.

The rock-shaft has secured thereto a pair of standards or uprights 0, each standard or upright having at its lower end a collar or hub by means of which and a suitable set screw or otherwise it is fixedly attached to the rock-shaft. The upper end of each standard or upright O has a socket or bearing 0, in which is mounted a shaft or rod D, the ends of the shaft in. the arrangement shown being upsetto form heads (1, by which the shaft or rod D is held in its bearings against end movement. Each end of the rock-shaft or rod D has fixed thereto-the side bars e of a yoke-frame E, and, as shown, the fixed end of each side bar e is located between the bearing a for the shaft or rod D and the u set end (2 of such shaft or rod. The yoke-Frame E consists of side bars e and an end bar e at the free end of the frame, and, as shown, in order to furnish additional strength each side bar 6 has a flange or right-angle piece 6 which, however, is not a necessity otherwise than for additional strength.

A stirrup-F is attached to the end bar e of the yoke-frame, and this stirrup consists of side bars f and an end barf, and each side bar has a turned end or flange f by means of which and suitable rivets or otherwise the stirrup is attached to the end bar 6 of the frame, and, as shown, at the free end of the yoke-frame on each side bar eis secureda late f having a depending ear f 4 with a ho e, in which ears is mounted an apron. (Not shown.) The ejector and centering roller G is located in the stirrup F, and this roller G has at each end a j ournal-pin 9, one of the'journal-pins entering an eye or bearing 9 on the cross-bar f of the stirrup and the other journal-pin g entering a bearing or eye 9 on the cross-bar e of the yoke-frame.

The carriage formed of the yoke-frame E and stirrup F for the ejector G is to be yieldably supported, so that it'willyield when required and will be returned to its engaging position when required. This carriage or support for the ejector in the construction shown is yieldably supported against dropping too far and also held in operative position for the ejector by a fiat spring H, one end of whichis attached to a stud or. pin h, projecting out from an upright or'standard C, and the other end of which is attached to a stud or pin it, projecting out from a side bar 6 of the yoke-frame. The .-body of the spring passes the stud h forward of a pin 72?, sothat the upper portion of the body of the spring has an upward curve by which it has a lifting actionon the swinging yoke-frame, by which the frame will be pressed constantly upward to the limit of the spring, holding the roller normally raised, and at the same time the yieldiof the spring is sufficient to allow the roller to. be forced down in use. It will be seen by this arrangement that the spring H furnishes a yieldable support for the ejector through its carriage, and this support from the spring is constant, as the spring travels with the uprights or standards and with the yoke-frame, and at the same time the spring is free to yield as the ejector is forced downward, giving the necessary resistance to the spring to return the ejector to normal position, when the depressing force is removed from the engagement therewith. It will further be seen that the carriage for the ejector is free to rise and fall with the rockshaft or rod D as a pivot, and that the rockshaft or rod D has a fixed relation with the rock-shaft B for supporting the standards or uprights C, which furnishes a double pivot for the carriage, one through the rock of the shaft B, which carries the uprights or stand ards to and fro, and another through the rock-shaft 0r rod D, which allows the yokeframe to rise and fall, and that both movements are independent of each other, but at the same time the rock of the shaft or rod D is dependent on the rock of the shaft moving the standards or uprights. This arrangement gives a positive rock by which the ejector is advanced and receded and a positive swing by which the ejector is free to rise and fall, and these two movements of the ejector render the operation of the ejector positive and reliable, one rock movement operating the ejector to discharge the article to be vended and the other rock movement insuring the release and engagement of the ejector with the carrier of the vendable articles. 1

The return of the rock-shaft B to swing the uprights or standards C forwardly at their upper ends should be controlled so as to prevent a too quick return of the ejector or discharge-roller to its normal position. This slow return or back rock of the shaft B from the stud h to' carriage of B in is obtainedby a lever I, having at its lower end a socket i, by means of which the lever is fixedly attached to the end of the rockshaft B by a cross-pin i passing through the socket i and the end of the shaft. At the front of the plate A is a standard or post J, having at its lower end a flange or foot 7', by means of which it is fixedly attached to the base-plate. This standard J and the lever I are in line with each other. The upper end j of the standard J has attached thereto by a pin or pivot 7c the stem 1c of a plun or K of a dash-pot, the movable section K of which is attached by cars k and a pin or pivot k to the upper end of the lever I, so that with the outward movement of the upper the lever I the cylinder or movable section K of the dash-pot will travel outwardly on the plunger or fixed section of the dash-pot.

The lever I is returned by a coil-spring J, one end of which is hooked into one of a series of holes 4? in the lever and the other one of which is hooked into one of a series of holes j in the post, the holes serving as a means for adjusting the spring so as to give a greater or less force in action. This coilspring J is expanded with the backward movement of the lever I and strain sufficient to exert a force to return the lever to normal position, and with the return I of the lever I to normal position the action of the dash-pot prevents a too rapid or quick return of the lever to its normalposition and preventing the rock-shaft B, and with it the the ejector or roller-discharger, being returned too quickly, thus preventing a jar on the return movement of the ejector or roller-discharger.

The discharging mechanism is located in juxtarelation to a package-carrier, and the package-carrier, as shown, mounted at its lower end in a step or bearing Z and having at its upper end a collar Z, "and from the upper end of the shaft a brace or support L extends and 'is connected at its lower end to the base A of the machine, and,

has a'shaft L end of placed under a as shown, the braceis held in-position between the collar Z and a pin 1 passing through the end of the shaft, thus giving the shaft a firm bearing at both its upper and lower ends. a A package-carrier M is fixedly connected with the shaft and consistsof a plurality'of receptacles 'm, each receptacle adapted to carry the articles to be vended. A plate N, having a hub a, is attached to the shaft by a cross-pin n, and this plate has secured to its under face a metal or other ring N, having-ears or flanges n and n for the attachment of the receptacles or compartments m to the support. A plate or disk 0, having a hub 0, is attached to the shaft by a cross-pin 0 andthis-disk has secured thereto a ring of metal or other material O, having ears 0 for attachment of the straight faces and curved faces, the faces forming depressions p to receive the the ring; The disk or plate N and the. disk .or plate 0, in connection with the rings N and 0'',

whole so as to revolve periphery of the discharging-roller lock and hold the package-carrier in direct line for a compartment thereof to be in alinement with the discharge-roller, so that the advance of the discharge-roller will remove an article from the compartment or receptacle to be delivered to the purchaser. The package-carrier has a circumferential wall or flange Q, attached to the carrier by supports or braces g and which furnishes a grab by means of which the purchaser can revolve the package-carrier into position for the desired receptacle or compartment m to be in line with the discharge-roller, so that on depositing the proper coin the dischargeroller can be advanced to remove the package or article from the compartment for delivery to the purchaser.

The use of the p ackage-carrier in connection with the discharge-roller will be readily understood from the foregoing description and the description of the operation of the discharge-roller.

The operation, briefly, is as follows: The ejector or discharge-roller G is held in its normally raised position by the action of the spring H, and when in its raised position on the backward movement of the standards or uprights O the carriage in which the ejector or discharge-roller is mounted will be carried rearwardly for the ejector to act and. discharge the lowermost one of the articles. The throw of the standards G at their upper end is sufficient to move the ejecting-roller G the distance to discharge a package from the commodity-carrier, and the return movement of the standards C carries the ejectingroller G into a position to engage with a new package and discharge such package with the rearward movement of the upper ends of the standards. the shaft B, and the frame also swings on or with the cross-rod D, giving the carriage, which supports the ejector or roller G, a double oscillation, thus guarding effectually against rigidity of movement in operating the ejector or ejecting-roller both in its advance and in its return movements.

The drawings, Fig. 2, show a plan view of a coin receiver or cradle and of a plunger to engage the coin in the receiver or cradle and rock the shaft B to swing the frame or support of the ejector or ejecting-roller. The coin-receiver L has on opposite sides of its The standards swing with.

K as to have the end of interior spiral ribs Z, down which the deposited coin travels vertically edgewise and is turned crosswise of its entered position, so as to stand in such relation with the plunger the plunger engage the face of the coin when the plunger is advanced. The plunger K is carried by an arm 7c, mounted at its lower end loosely on the rock-shaft, and the plunger is advanced and receded by swinging the arm 16 on the rockshaft B through any suitable mechanism.

The receiver or cradle has throughits wall atthe top a slot Z for entering the com into the spiral pathway to descend therein. A detail construction and illustration of the coincontrolled mechanism is not deemed necessary, as the present invention is confined to the delivery mechanism, and any construction of coin-controlled mechanism that will rock the shaft B and swing the standards C can be employed.
